What Causes the Impact Noise When Shifting into Reverse Gear in a 7-Speed DSG Dry Clutch Transmission?
1 Answers
Here are the specific reasons for the impact noise when shifting into reverse gear in a 7-speed DSG dry clutch transmission: 1. Cold Start: During a cold start, the transmission fluid has poor flowability, and the internal gears are not sufficiently lubricated, resulting in abnormal noises during gear shifts. 2. Aged Transmission Fluid: Transmission fluid, like engine oil, requires regular replacement. When the fluid ages, its lubrication capability decreases, leading to noticeable impact sensations and abnormal noises during gear shifts. 3. Worn Transmission Gears: Improper vehicle usage by some owners can cause wear on the transmission gears. When the gears are worn, metallic noises may occur during gear shifts.
